  1. 1. A sub-5 fs 100 TW optical parametric synthesizer

    Författare :Peter Fischer; Laszlo Veisz; Ove Axner; Cord L. Arnold; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical parametric amplification OPA ; optical parametric synthesizer OPS optimization; energy stability; carrier envelop phase stability; temporal intensity contrast; saturation; fewcycle; tera watt; fysik; Physics;

    Sammanfattning : State-of-the-art ultrashort light sources in the visible and near-infrared spectral regions provide direct access to the femtosecond realm, thereby enabling understanding and control of electronic processes within matter. On the other hand, ultra-intense light pulses lead to the emergence of relativistic electron motion and many related phenomena, such as electron & ion acceleration and high-order harmonic generation in plasmas.

    Nyckelord :HUMANIORA; HUMANITIES; psychogeography; sound art; electroacoustic music; urban activism; violin; transposition; Stockholm; music; organ; synthesizers; improvised music; urban studies; sound installation; musik; violin; fiol; orgel; impromusik; improvisation; electroakusitsk musik; psykogeografi; urbana studier; stadsgestaltning; urbana aktivism; ljudkonst; ljud installationer; synthesizer; transponering; Stockholm;

    Sammanfattning : The towers of the Stockholm skyline twine with radio transmissions, flying out over the city, drifting down through the streets and sinking into the underground telephone system below. Stockholm has buildings that have been there for centuries, but is also full of modern and contemporary architectures, all jostling for their place in parallel collective memory. LÄS MER

  4. 3. Integrated Frequency Synthesis for Convergent Wireless Solutions

    Författare :Jad G. Atallah; Mohammed Ismail Elnaggar; Erik Bruun; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless; transceiver; Bluetooth; DECT; GSM; 3G; LTE; WLAN; WiMAX; multi-standard; vertical handover; Sniffer; frequency synthesizer; phase-locked loop; PLL; sigma-delta; calibration; Electronics; Elektronik;

    Sammanfattning : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.

  5. 4. On PLL Modeling and Design in Nanometer‐Scale CMOS

    Författare :Anders Jakobsson; Shaofang Gong; Adriana Serban; Hannu Tenhunen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-locked loop; Frequency synthesizer; Calibration; Modelling; Quantized-state system; Phase interpolator; Sub-sampling PLL;

    Sammanfattning : Integrated circuits play a vital role in our everyday lives, from wireless gadgets and multimedia players to sensors and processors that control vital infrastructure. Since most electronic circuits need a clean, stable clock or carrier to function, one of the most important components of integrated circuits is the phase-locked loop. LÄS MER

  7. 5. Design and Analysis of Charge-Pump Bases Frequency Synthsizers

    Författare :Tord Johnson; Svante Signell; Mälardalens högskola; []
    Nyckelord :Datavetenskap;

    Sammanfattning : Most telecommunication systems employ modulation techniques that require the transceiver to be capable of accurately estimating the phase of the transmission signal. The frequency synthesizer is a key element and extensively utilized to synthesize frequencies for such radio-frequency communication systems. LÄS MER
